Hi Trevor,
watching for keyDownEvent is correct.
In my program, I have a list of entries and a search field ( much like
the list view in the Adress Book app )
My code for handling this situation is as follows:
case keyDownEvent:
if (event->data.keyDown.chr == pageUpChr) {
PageScroll(winUp);
} else if (event->data.keyDown.chr == pageDownChr) {
PageScroll(winDown);
} else {
FormType* frm = FrmGetActiveForm();
UInt16 fieldFocus = FrmGetFocus(frm);
if (fieldFocus != noFocus &&
FrmGetObjectId(frm, fieldFocus) ==
ENumListFormFindField) {
FieldType* enumField =
(FieldType*)FrmGetObjectPtr(frm,
FrmGetObjectIndex(frm,
ENumListFormFindField));
if (FldHandleEvent(enumField, event)) {
SelectFromFind(); // gets the field
content and highlights the
list/table entry accordingly
handled = true;
}
}
}
break;
Good Luck,
Juergen
